Sungrow Unveils 1500V SG250HX String Inverter at Intersolar Europe 2019

Sungrow, one of the leading inverter solution supplier for renewable energy projects globally, has unveiled its latest 1500Vdc string inverter SG250HX at Intersolar Europe 2019.

Sungrow SG250HX String Inverter

The SG250HX, the company claims, is the world’s most powerful 1500Vdc string inverter, featuring a high capacity of 250kW. It comes with the high voltage of 1500Vdc and 800Vac, enabling cost saving on DC and AC cables. The product is of maximum efficiency of 99% and compatible with bi-facial modules, offering a higher yield. The system features 12 MPPTs and a flexible block design allowing for up to 6.3 MW blocks, making it an ideal solution for hilly utility-scale applications.

With a smart forced air-cooling technology, the SG250HX can operate without derating at extremely high temperatures. The system is also inserted with fault diagnostic and IV-curve scan function, making it easier for operation and maintenance. Embedded anti-PID function will lead to much less module degradation. Also, the improved Power Line Communication (PLC) shall decrease installation cost without excessive communication wiring. In a bid to co-work with the probable storage segment, the inverter can be connected to storage systems with equipped storage interface.

“Sungrow is excited to bring forth another disruptive string inverter technology to Europe, maximising ROI for our customers at unforeseen levels,” said Stefan Froboese, Technical Director, Sungrow EMEA. “Europe is witnessing an increase in activity for unsubsidised solar portfolios, whilst private renewable PPAs are poised to become more prevalent. Sungrow is dedicated to paving the way for grid parity across Europe with growing technical innovations and accelerating the global step to fulfil its corporate mission of “clean power for all.”

Recently, the company signed an agreement with Enel Green Power Chile to supply its featured 1500V inverter solutions to a 400 MW PV farm in Copiapó, Chile. The solar PV farm in Copiapó, once completed, is expected to be the largest PV plant in the South American nation.
